摘要： An optical system comprises an objective (1) and a detector (7) or reticle interacting with this via a stop aperture (6a). A decentralising function for the objective and stop in relation to the detector or the reticle is arranged to prevent beams (Sa) reflected by the surface (7a) or surfaces of the detector or reticle from passing back through the stop aperture. No reflectance or very small reflectance is thus obtained from the optical system, which means that detection of the equipment utilizing the system is made essentially more difficult in a way that is simple as far as technology and economics are concerned.

摘要： With the optical detection of a difference between both sides of a divided focus spot light of a section on a self-luminous body, the light from a light source point of said section on a self-luminous body is represented as a graph having a more peculiar point or a sharper point within the diffraction limit of the objective than the light intensity distribution graph of the focus spot light from said light source point of said section. With three values M, N and O from said optical detection of a difference in both sides of a divided focus spot light of said section on a self-luminous body, the brightness of a photo-image of said object on a self-luminous body is obtained by the value (Mnull2NnullO).

摘要： A lens apparatus for projection includes a plurality of lenses on an optical axis. A shading plate 11 for covering the peripheral portion of the lens to block off light entering the peripheral portion is provided as a single member on the optical axis with the lenses to omit an inking process. In addition, the shading plate 11 is integrally provided with a contrast compensating plate 13 for compensating a projected image, so that it is not required to provide any portions for supporting the contrast compensating plate 13. Moreover, a shading wall 23 for blocking off light leaking out of the peripheral portion of the lens is provided on the peripheral portion of the shading plate 11. Thus, it is possible to provide a lens apparatus for projection, which has a simple structure and which can be easily assembled to reduce the producing costs.
